Classify the types of force based on their application .

Explanation

Based on the direction in which the forces act, they can be classified into two types as :
(i) Like parallel forces and (ii) Unlike parallel forces.
Like parallel forces : Two or more forces of equal or unequal magnitude acting along the same direction, parallel to each other are called like parallel forces.
Unlike parallel forces : If two or more equal forces or unequal forces act along opposite directions parallel to each other, then they are called unlike parallel forces.
